GRATE FOR REFUSE-'BURNERS.

SPECIFICATION forming part of Letters Patent No. 377,651, dated February 7, L888.

Application filed April 28, 1887. Serial No.236A84. (No model.)

To all whom it may concern:

Be it known that I, EDGAR G. TEED, a citizen of the'UnitedStat-es, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in' Grates for Refuse-Burners, of which the following is a specification.

This invention has for itsobject to provide novel. means for rapidly and efficiently consuming garbage and other refuse matter; and to such end the invention consists in the features of construction and combination of devices, hereinafter describedand claimed, reference being made to the accompanying drawings, in which-- Figure 1 represents a vertical section of a refuse-burner constructed according to my invention. Fig. '2 is a front elevation of the same. Fig. 3 is a longitudinal section in the plane mac, Fig. 1. Fig. 4 is a sectional plan view of a grate,drawn to a larger scale than the preceding figures. Fig. 5 is a section thereof in the plane 1 y, Fig. 4.

. Similar letters indicate corresponding parts.

In th-edrawings, theletters A A designate the walls of a furnace constructed in the usual manner.

Bis the ash-pit, and G is the fire-box.

The fire-grate D is of the usual construction, and above said grate is arranged a supplementary or garbage-supporting grate, E, con- I sisting of two or more sections, E E,which can be turned about central axes, in a manner to be hereinafter described. Above the grates E E is situated a similar grate, F F, and, if desired, a third grate or several more may be arranged in tiers.

At the top of the furnace, and directly over the supplementary grates, is located a hopper, B, containing suitable pivoted and weighted gates, B B which open to dump the garbage upon the grate F, but close immediately afterward to prevent the escape of gases. A flue or flucs, A, lead off the products'of combustion and other gases.

The flames from a coal or wood fire on the grate D come into contact with and ignite the refuse matter held loosely in suspension upon the garbage-supporting grates E and F, and the free circulation of air and flame through the suspended matter causes it to be more grate, E.

The intense heat caused by the combustion of the matter suspended on the grates E and F would soon cause their destruction. vent this I provide for a circulation of water To prematter thereon can be conveyed to the lower through said grates, and to keep all portions of the grate in a nearly uniform temperature I construct the grate as follows:

Referring to Figs. 4. and 5, the grate-bars 6 each consist of a tube closed at one end and provided at its other end with a screw-thread or other means to attach it to a tubular body, G, in the center of the grate. Through the center of the body G extends longitudinally a supply-pipe, H, which is provided-with lateral tubes f, extending into the gratebars e and nearly to the ends of the same. At the rear end of the grate this supply-pipe is closed by a suitable plug, h, so that the water forced into said pipe can leave it through the tubes f only, and,fpassing through the grate-bars 6, enter an annular discharge-chamber, 1', formed between the body G and' the supply-pipe H. The hot Water or steam, as the case may be,

enter the outlet-pipe I, which may be a con-' tinuation of the supply-pipe H, through openings or perforations h, located back of the plug h.

In order that the grate may be rocked or rotated freely, I extend the tubular body G outward beyond the grate-bars to form tri1nnions y for the grate, and the supply-pipe H is made sectional,the sections H, H, and I having abutting flanges. Stuffing-glands I I, Fig. 1, are provided at the ends of the trunnions g, and to prevent the screwing up of the glands from pressing the flanges of the pipesections H, H, and I together, so as to effect the turning of the body G about thepipe-sections H and I, I secure abutment-rings J J inward to the trunnion g by screws j j, which rings take up the strain exerted by screwing up the glands.

In practice, when several grate-sections are arranged in a horizontal plane, as in Figs. 2 and 3, I provide water-chambers L and L at the front and rear of the furnace, with which the pipes H and I of the respective gratesections are connected. Check-valves Z, Fig. 3, are inserted in the pipes H behind the waterchambers L. The water entering the grates is converted into steam during its passage through the same, and such steam is led from the same by a common steam-pipe, S, Fig. 8, and conducted to a steam'dome, (not shown in the drawings,) when it is used for actuating a motor. If, however, there is no use for motive power, it is led to a condenser and then used repeatedly for cooling the grates.

The water may be forced through the grates either by a pump or drawn from an elevated reservoir. To turn the grates, levers N, engaging suitable ratchetplates, n,or other wellknown means, can be employed.

WVhat Icl'aim as new, and desire to secure by Letters Patent, is-

1. The combination,with a furnace for burning refuse matter, of a dumping-grate comprising a tubular body having tubular gratebars and end trunnions journaled in the walls of the furnace, a Water-supply pipe extending lengthwise through the tubular body for dis charging water into said tubular grate-bars, a plug in one end of the water-pipe, and means for the escape of the water behind the plug, substantially as described.

2. In a grate, the combination of the tubular body G, the tubular grate-bars secured thereto, and the supply-pipe H, closed at one end and provided with lateral tubes f, entering the grate-bars, said supply-pipe forming with the tubular body G an annular discharge chamber, substantially as shown and described.

3. In a rocking grate, the combination of the tubular body G, the tubular grate-bars secured thereto, the supply-pipe H, closed at 40 one end and provided with lateral tubes f, entering the grate-bars,said supply-pipe forming with the tubular body G an annular discharge-chamber, the sections H and I, and the glands I I, substantially as and for the purpose specified.

4. In a grate, the combination of the tubular body G, the tubular gratebars secured thereto, and the supply-pipe H,closed near one end, the lateral tubes f,entering the grate-bars, said supply-pipe forming a discharge-chamber with thetubular body, and the openings in the supply-pipe beyond the plug, whereby the discharge-chamber is connected with said supply-pipe beyond the plug, substantially as shown and described.

5. The combination, with a grate constructed with a tubular body, G, of the sectional supply-pipe H, the glands I, and the abutment rings J, secured within and to said tubular body, substantially as and for the purposeset forth.

In testimony whereof I have hereunto set my hand and seal'in the presence of two subscribing witnesses.
